Creating a wired network is a mess of sorting through different networking parts and pieces and figuring out which ones work best with each other. Even the choice of cables isn’t obvious, as CAT5e and CAT6 are two potential cable options. However, their compatibility with panels varies, and if you have a CAT6 patch panel, it will influence your choice of cable.
So, how exactly does the patch panel you have influence which cable you should use? Where do CAT5e and CAT6 cables fall when it comes to performance? Can you use a CAT5e Cable in a CAT6 patch panel? Keep reading to find out the answers to all of these questions!
What Is a CAT5e Cable?
CAT5e is a standard that was created for network cables. The CAT5e designation stands for Category 5e or Category 5 Enhanced.
Since this is just a cable standard, it is something that can be created by multiple different companies. There is no universal cable created by one company but, rather, a blueprint that all companies follow to create a cable with these specifications.
This cable represents an improvement over the previous CAT5 cable standard. The improvements brought speeds around ten times better than what was available before. This new cable standard also improved the ability of the cable to transmit information over longer distances without interference. Specifically, these cables can support gigabit networks at distances running up to 100 meters.
What Is a CAT6 Cable?
CAT6 stands for Category 6 and was released a few years after the release of the CAT5e cable standard. The CAT6 standard is very similar to the CAT5e cable standard. Both are cable standards designed to accomplish a nearly identical purpose. However, the way they go about doing this is slightly different.
Specifically, the CAT6 cable standard represents the next step in the progression of this cable standard. This cable standard improved how the cable handles and transmits data.
When it comes to the ability to support gigabit networks over long distances, CAT6 and CAT5e cables are relatively similar. Like CAT5e cables, CAT6 cables also support gigabit networks of up to 100 meters.
Where the improvement lies is in the ability to handle 10-gigabit networks. CAT6 cables are able to be used in 10-gigabit networks for more limited distances. They can’t handle these networks for the 100 meters they can handle gigabit networks but can still do so in shorter ones.

Is Using a CAT5e Cable in a CAT6 Patch Panel Possible?
The short answer is yes. You can absolutely use a CAT5e cable in a CAT6 patch panel. The cables themselves are designed to be relatively interchangeable and will work on either type of panel. The CAT6 wire is thicker and may not initially look like it will work, but the connection is all that matters, and the connection is the part that works.
This is because the CAT6 cables and their respective panels were designed with backward compatibility in mind. In fact, the cables are so interchangeable that you could run a CAT6 cable in a CAT5e panel and a CAT5e cable in a CAT6 panel. The backward compatibility between the cables allows any of these combinations to be possible.
How Is Performance When Using These Cables?
How do both of these cables compare to each other? Do the improvements provided by the CAT6 cable provide that much benefit over the CAT5e cable? What does the CAT5e vs. CAT6 debate come down to?
Let’s start with speed, which is what matters most to the majority of people. CAT5e and CAT6 cables are both rated for speeds of 1 gigabit for distances of 100 meters. So, when talking about a long connection, performance will be somewhat similar no matter which cable you are using.
The difference in speed will come from the bandwidth. CAT6 cables are designed for frequencies up to 250 MHz, while CAT5e cables are only designed for frequencies up to 100 MHz. This increase gives CAT6 cables the ability to process more data in the same amount of time. While this will not have as much of an impact on overall speed, it will still result in better performance when using a CAT6 cable.
On top of all of this, the structure of the CAT6 cable reduces the amount of crosstalk. This reduces the number of errors that are made as data is transmitted.
The differences really become obvious when talking about shorter distances. When used for shorter distances, CAT6 cables offer significant increases in speed over their CAT5e counterparts. Because of this, they are often used within the core of a network, as the short distances there make it easy to take advantage of this feature.
Should You Use a CAT5e Cable in a CAT6 Patch Panel?
So, a CAT5e cable can be used in a CAT6 patch panel. However, a CAT6 cable is better than a CAT5e cable. Does this mean you should use a CAT5e or CAT6 cable when using a CAT6 patch panel?
Ideally, when picking an ethernet cable, you should always use a CAT6 cable with a CAT6 patch panel. When using a CAT5e cable in a network, the network will default to using the speeds it provides as the base speeds. This limits what your CAT6 patch panel is capable of. It is still possible to use a CAT5e cable in this network, but it will slow things down.
There is also the potential that, as networking speeds improve, the advantages provided by a CAT6 cable will become more prominent. 10-gigabit speeds seem like overkill now, but some predictions indicate they might become standard in around a decade. If this happens, you may want to upgrade your CAT5e cables in favor of CAT6 cables anyway. So, to prevent future dilemmas, going with the better cable in the present is the better choice.

Using a CAT5e Cable in a CAT6 Patch Panel
It is possible to use a CAT5e cable in a CAT6 patch panel. However, doing so will limit what the network is capable of and, thus, slightly limit speeds. Because of this, it is always ideal to use a CAT6 cable with a CAT6 patch panel.
